一般描述
两亲性嵌段共聚物 (AmBC) 由两种化学结构不同的均聚物嵌段组成。其中一个是亲水性的,另一个是疏水性的。这些大分子在水性介质中溶解时具有自组装的属性。PEG-PLGA 是一种最常用的可生物降解的两亲性嵌段共聚物,用于药物输送。PEG 是亲水性部分,PLGA 是疏水性部分。
应用
形成“隐形”聚乙二醇化微粒
用于合成用于药物差异递送和控释的靶向纳米粒子。
特点和优势
- 生物相容性好,免疫原性低,可降解性好。
- 通过改变嵌段共聚物链段大小以适应特定的应用,可以很容易地调节性质。

There has been progressively heightened interest in the development of targeted nanoparticles (NPs) for differential delivery and controlled release of drugs. Despite nearly three decades of research, approaches to reproducibly formulate targeted NPs with the optimal biophysicochemical properties have remained
